https://github.com/cplusplus/sender-receiver/pull/154 updates the sender concept to use using sender_concept = std::execution::sender_t instead of the old using is_sender = void (and the same for receivers). We should update our senders and receivers to use both for compatibility across stdexec versions. The newest commits of stdexec look for both, but I think we can support both for a while.
